Chapter 17 LAN Setup

Your ZyAIR checks the MAC address of the wireless station device against a list of allowed or 
denied MAC addresses. However, intruders could fake allowed MAC addresses so MAC-
based authentication is less secure than EAP authentication. 

Follow the steps below to create the MAC address table on your ZyAIR.

1 From the main menu, enter 3 to open Menu 3 – LAN Setup.

2 Enter 5 to display Menu 3.5 – Wireless LAN Setup. 

Edit SSID Profile

Use [SPACE BAR] to choose Yes and press [ENTER] to go to Menu 3.5.6 - SSID Profile 

Edit.  This field is only available when you select MESSID in the Operating Mode field.

Select SSID Profile

Use [SPACE BAR] to choose an SSID profile.  This field is only available when you select 

Access Point in the Operating Mode field.

Preamble 

Use [SPACE BAR] to choose a preamble type. Choices are Long, Short and Dynamic. 

The default setting is Long.
See the section on preamble for more information.

802.11 Mode

Select B Only to allow only IEEE 802.11b compliant WLAN devices to associate with the 

ZyAIR.
Select G Only to allow only IEEE 802.11g compliant WLAN devices to associate with the 

ZyAIR.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices to 

associate with the ZyAIR. The transmission rate of your ZyAIR might be reduced.

Max. Frame Burst 

Enable Maximum Frame Burst to help eliminate collisions in mixed-mode networks 

(networks with both IEEE 802.11g and IEEE 802.11b traffic) and enhance the 

performance of both pure IEEE 802.11g and mixed IEEE 802.11b/g networks. Maximum 

Frame Burst sets the maximum time, in microseconds, that the ZyAIR transmits IEEE 

802.11g wireless traffic only. 
Type the maximum frame burst between 0 and 1800 (650, 1000 or 1800 recommended). 

Enter 0 to disable this feature.

Breathing LED

Select Yes to enable the Breathing LED, also known as the ZyAIR LED.
The blue ZyAIR LED is on when the ZyAIR is on and blinks (or breaths) when data is being 

transmitted to/from its wireless stations. Clear the check box to turn this LED off even 

when the ZyAIR is on and data is being transmitted/received.

Block Intra-BSS Traffic

Intra-BSS traffic is traffic between wireless stations in the same BSS. Select No to allow 

Intra-BSS traffic, select Yes to block all Intra-BSS traffic. 

Output Power

Set the output power of the ZyAIR in this field. If there is a high density of APs within an 

area, decrease the output power of the ZyAIR to reduce interference with other APs.The 

options are 17dBm (50mW), 15dBm (32mW), 13dBm (20mW), 11dBm (12.6mW) or 7dBm 

(5mW) for IEEE802.11b mode and 13dBm (20mW), 11dBm (12.6mW), 9dBm (7.9mW), 

7dBm (5mW) or 3dBm (2mW) for IEEE802.11g mode.

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC to cancel” to 

save your configuration or press [ESC] to cancel and go back to the previous screen.
